.SHORT TERM...
(This afternoon through Monday)
Issued at 127 PM EST Sun Dec 7 2025

Fog continues to hold across much of the metro area with patches
of dense fog also further south and in the northwest. Satellite
shows dense low cloud cover across much of the area and in valleys
of north Georgia. High cirrus, which moved in this morning, have
acted as a blanket to keep the sun from burning off much of the
fog and cloud cover. This required both an extension of the dense
fog advisory earlier as well as the issuance of a special weather
statement for patchy dense fog with vsby <1SM.

Moisture will continue to stream into the area from the southwest
aloft ahead of the next quick shortwave overnight tonight. A line
of showers will move through the area tonight bringing light
accumulations of generally <0.4" for much of the CWA. Cloud
ceilings will remain low, holding dreary conditions well into
tomorrow morning and early afternoon.

Dry air moving in behind the system will help to clear out some
clouds as we go into Monday night and Tuesday morning, though this
is short lived. Winds out of the north will quickly transition
back to near surface east flow, redeveloping the wedge and
bringing a return to dreary cloudy conditions. Light wrap around
moisture into the wedge in the far northeast mountains of the CWA
may bring some light precipitation Monday night, however PoPs
remain at a meager 15-20% for the small area. Should anything
fall, temperatures may be close to freezing bringing a light
wintry mix. No accumulations are expected and impacts, should
anything even fall, will be limited to none. In all likelihood,
precipitation may only be likely in a warmer solution which would
not promote any frozen precip.

.LONG TERM...
(Tuesday morning through next Saturday)
Issued at 127 PM EST Sun Dec 7 2025

Tuesday and Wednesday are still on track to bring dry, sunny to
mostly sunny conditions. Wednesday still looks to be noticeably
warmer than Tuesday, as the airmass modifies and surface/low-
level flow shifts from northerly to westerly in response to a
northern stream shortwave/jet streak that will dive southward and
eastward across the Ohio/Tennessee River Valleys. PoPs are lower
on Thursday (only up to 20%) with this forecast package, and
relegated to along and north of I-85, as the Pacific moisture
accompanying said shortwave looks to be meager this far south.
Showers (if they even occur) should be light and not amount to
much rainfall.

Ensemble guidance shows a stronger shortwave/jet streak barreling
eastward across the central tier of the eastern CONUS Thursday
evening into the weekend. This feature will drive a strong
northwest flow, cold-air advection (CAA) response at/near the
surface, evidenced by our current forecast for overnight/early
morning lows to go from the mid-30s to mid-40s on Friday to the
upper teens to lower 30s on Saturday. If this forecast comes to
fruition, we could be greeted with some of the coldest air of the
season thus far.
